- Exponents and Roots
- Exponentiation
Multiplying a numberseveral times, such as , is called exponentiation of . In , is called the base of the exponent, and is called the exponent. -th Root
For a real numberand a natural number , a number that, when raised to the power , equals , i.e., a solution to the equation , is called the -th root of . The square root, cube root, and higher roots of are collectively referred to as the roots of . - Relationship between the
-th root of and ( -th Root of ) is even 0 Does not exist is odd 0 - Properties of Roots
When, , and are integers greater than or equal to 2: (where is a positive integer) - Extension of Exponents
- When the exponent is 0 or a negative integer
Forand a positive integer: - When the exponent is a rational number
